Answer:

x = 18

Step-by-step explanation:

Twice a number becomes 2x, decreased by 4 becomes -4, and combined those terms equal 32.

2x - 4 = 32

2x - 4 + 4 = 32 + 4 (isolate the variable)

2x = 36

x = 18

Answer:

$\boxed{\bold{-25}}$

Step-by-step explanation:

Remove parenthesis: (a) = a

$\bold{\frac{-5^2+10^2}{-2\cdot \:5\cdot \:3+3^3}}$

$\bold{-5^2+10^2: \ 75}$

$\bold{\frac{75}{-2\cdot \:5\cdot \:3+3^3}}$

$\bold{-2\cdot \:5\cdot \:3+3^3: \ -3}$

$\bold{\frac{75}{-3}}$

Apply fraction rule: $\bold{\frac{a}{-b}=-\frac{a}{b}}$

$\bold{-\frac{75}{3}}$

Divide $\bold{\:\frac{75}{3}: \ 25}$

$\bold{-25}$

A box contains 5 red chips, 3 blue chips, and 7 white chips. A chip is randomly selected, replaced, and a second chip is selecte

Basile [38]

So add the number of chips together
5+3+7=15
So the chance of a red chip is 5/15
Blue 3/15
White 7/15
So the blue chips would be 3/15 chance
So take away one chip 14
So 7/14
The awnsers is
The probability of selecting a blue chip will be 3/15 and for a white chip it is 7/14
